I haven’t tried a brand new project yet, but existing projects that use video with thumbnails have zoom lag in C9.5. The mixer zooming and scrolling is just as painful as it was in 9, and also scrolling through tracks in the project window is a a bit jerky. I spoke too soon before, hadn’t really put it through its paces yet.
Some things are improved, like zooming in and out in the project window, which is awesome, and it feels a touch snappier overall…but there is still major work to do. I trust (hope) that they’re on it. I’m feeling exasperated.
